  The discrimination device 22 has an image sensor to determine the denomination and authenticity of the bill, and the image sensor reads the image of the paper sheet conveyed to the image sensor, and based on the image, the paper sheet Determine the type and authenticity. The temporary storage 23 temporarily stores the sheets that have passed the discrimination by the discrimination device 22. The temporary storage 23 separates the stack of banknotes transported from the transport path 27 and the stacked paper sheets one by one and delivers them to the transport path 27.

  The temporary return storage 24 temporarily stores paper sheets until the paper sheets which can not be discriminated by the discrimination device 22 are returned. The temporary storage for return 24 stacks and feeds the paper sheets in the same manner as the temporary storage 23. The reject storage 25 stores the paper sheets for which the type of the paper sheet could not be determined in the discrimination device 22, the counterfeit bill, and the paper sheets discriminated as the special cash voucher. The storages 26a to 26e store paper sheets by denomination. The storages 26a to 26e accumulate and store the sheets received from the conveyance path 27 when storing the sheets. Further, at the time of taking out the sheets, the accumulated sheets are separated one by one and fed out to the conveyance path 27. The storages 26a to 26e are carried out of the sheet handling apparatus 2 and used for operations such as recovery and replenishment of sheets. It is also possible to use one of the storages 26a to 26e for collection of counterfeit bills or storage of paper sheets that the user has forgotten to take.

  The transport path 27 is configured by a transport roller, a transport belt, and a guide plate to transport paper sheets, and there is a gate at the branch point that switches the transport direction. The conveyance roller and the conveyance belt are driven by a motor and are configured to be able to convey sheets in any direction at any speed, and there is a sensor in the middle of the conveyance path 27 to monitor the conveyance status of the sheets. It also makes it possible to detect paper jams.

  The discrimination device 22, the temporary storage 23, the temporary storage 24 for return, the reject storage 25, and the storages 26a to 26e are stored in a safe (not shown). The safe is formed of a thick metal plate for preventing theft, has a door with a key, and is opened at the time of operation of the storages 26a to 26e and at the time of maintenance management of the paper sheet handling apparatus 2 26e to a part of the sheet handling apparatus 2 can be pulled out.

  Next, the operation of the sheet handling apparatus 2 will be described. The sheet handling apparatus 2 realizes two steps of an operation of counting the number of sheets at the time of deposit transaction and an operation of conveying the sheets to the storage in the safe. FIG. 3 illustrates the counting operation of the sheet handling apparatus 2. The sheet handling apparatus 2 opens the shutter 211 of the deposit / withdrawal port 21 to form an input standby state of the sheet into the deposit / withdrawal port 21. When a sheet is inserted into the deposit / withdrawal port 21, the sheet handling apparatus 2 closes the shutter 211 and operates the pressing plate 213 to align the sheets within the deposit / withdrawal port 21. Thereafter, the separation roller 214 is rotated to separate the sheets one by one, and the feed rollers 215 sequentially feed the sheets to the transport path 27. In the transport path 27, the transport rollers on the transport path 27 and the transport belt transport the sheets along the path indicated by F, and the paper sheet is transferred to the temporary storage 23 or the temporary storage 24 for return. Species are stored. A discrimination device 22 exists in the middle of the transport path 27, and counting of paper sheets, type determination, and authenticity determination are performed.

  FIG. 4 is a view for explaining the storage operation of the sheet handling apparatus 2. When the transaction is established by the confirmation of the amount of money input from the user, the temporary storage 23 delivers the accumulated paper sheets to the transport path 27 one by one. The transport path 27 passes the received paper sheets through the discrimination device 22 again and transports the paper sheets to the storages 26a to 26e. The paper sheet is again subjected to discrimination of denomination and authenticity of the paper sheet by the discrimination device 22, and is distributed to the storages 26a to 26e according to the denomination and stored. At this time, for example, one of the storages 26a to 26e can be dedicated to the recovery of a sheet determined to be false in the authenticity determination.

  FIG. 5 illustrates the dispensing operation of the sheet handling apparatus 2. When the user confirms the dispensing transaction, the paper sheet handling apparatus 2 feeds out the paper sheets accumulated in the storages 26a to 26e to the conveyance path 27 one by one and receives and discharges the paper sheets. Transport to 21 The sheet handling apparatus 2 causes the feed roller 215 to pull in sheets from the transport path 27 to the deposit / withdrawal port 21, aligns and stacks the sheets, and then opens the shutter 211 to give the user a sheet of paper. Expose leaves.

  As shown in FIG. 6, in the deposit / withdrawal port 21, the shutter 211, the stack guide 212, the pressing plate 213, the separation roller 214, the feed roller 215, the sheet roller 216, the light projector 217, and the light receiver 218 And a light shielding cylinder 219 are provided. The light blocking cylinder 219 protects the light receiver 218 from external light (sunlight and / or illumination light) as described later, and suppresses the malfunction of the light receiver 218 by the external light.

  The shutter 211 is configured as a plate-like component, and controls access to the deposit / withdrawal port 21 by being slid in the opening / closing direction of the recess. The stack guide 212 is a plate-like member that tilts back and forth with the lower end as a fulcrum. The pressing plate 213 is a plate-like member that slides in the front-rear direction. The separation roller 214 is provided with a high friction member such as rubber on a part on the circumference. The feed roller 215 is configured as a rubber roller. The sheet roller 216 is provided with a plurality of blades made of rubber or a film-like member on its surface. The blades are flexible and configured to bend even when touching the stack guide 212, the pressing plate 213, the bottom surface, and the like.

  The light projector 217 has a configuration in which an LED and a lens cap are integrated, and emits light linearly to the light receiver 218 (light receiving sensor). As shown in FIG. 8, the light projector 217 is connected to the controller 52 via the light emission driver 50. The controller 52 controls the light emission driver 50 to control the light emission / non-light emission of the LED of the light projector 217. The light receiver 218 has a configuration in which a phototransistor and a lens cap are integrated, and outputs a detection signal to the controller 52 when light from the light projector 217 is detected. The controller 52 forms a shutter drive control signal based on the detection signal from the light receiver 218 and supplies the shutter drive control signal to the shutter driver 56. The shutter driver 56 controls the drive unit 58 (motor or solenoid) of the shutter to realize the opening / closing operation of the shutter 211.

  A light blocking cylinder 219 and a light receiver 218 according to FIG. 6 are shown enlarged in FIG. FIG. 7A is a perspective view of the connection structure of the light blocking cylinder 219 and the light receiver 218, and FIG. 7B is a cross sectional view thereof. The light shielding cylinder 219 is formed of a hollow cylinder made of a light shielding material, and the base end thereof is fixed to the end of the light receiver 218 on the light emitter 217 side along the light path from the light projector 217 to the light receiver 218. The light output from the light projector 217 travels in the light shielding cylinder 219 from the end of the light shielding cylinder 219 on the light projector 217 side, and reaches the light receiver 218 at the base end of the light shielding cylinder 219. The sheet handling apparatus 2 monitors the condition in the deposit / withdrawal port 21 based on the detection of the light output from the light emitter 217 by the light receiver 218. As shown in FIG. 6, when the sheet P is present in the deposit / withdrawal port 21, the output light from the light projector 217 can not reach the light receiver 218 by the sheet P, and conversely, the sheet P In the absence of light, the output light from the light projector 217 travels in the light blocking cylinder 219 toward the light receiver 218 and is detected by the light receiver 218. The presence or absence of the user's finger or palm in the deposit / withdrawal port 21 is also determined similarly to the paper sheet P. The sheet handling apparatus 2 maintains the shutter in the open state because the light receiver 218 can not detect the output light from the light projector 217 when the sheet or the finger is present in the cash slot 21. There is.

  As shown in FIG. 6, although the light receiver 218 is shielded from the external light 600 by the light shielding cylinder 219, since the deposit / withdrawal port 21 is inclined to the user side of the front, it enters into the deposit / withdrawal port 21. Depending on the degree of the incident angle, the external light 600 is reflected by the end of the light shielding cylinder 219 on the side of the light emitter 217 of the light shielding cylinder 219, and the reflected light 602 is propagated while repeatedly reflected in the light shielding cylinder 219 and received. Can cause the light receiver 218 to malfunction. Therefore, there is a possibility that the shutter may be closed despite the presence of paper sheets and fingers in the deposit / withdrawal port 21.

  Therefore, as shown in FIGS. 9 and 10, the end of the light shielding cylinder 219 on the side of the light projector 217 is formed in such a manner as to suppress the entrance of external light into the light shielding cylinder. That is, the end of the light shielding cylinder 219 on the side of the light emitter 217 is retracted or offset from the incident direction 600 of the external light to the light receiver 218 side, so that the base of the incident direction of the external light in the radial direction of the light shielding cylinder 219 The tip end end 612 in the incident direction of the external light is set to be retracted toward the light receiver 218 more than the end end 610. In other words, for example, a tapered or substantially tapered open end 219A is formed at the end of the light blocking cylinder 219 at the light emitter 217 side, and the open end 219A is outside the traveling direction 600 of external light, for example, the gravity direction or , I decided to turn in the direction of gravity. Therefore, the reflection possible end (see FIG. 6) of the external light at the end of the light blocking cylinder 219 at the light emitter 217 side can be hidden from the incident direction 600 of the external light. It is suppressed that the light is reflected and propagated in the light shielding cylinder 219. The angle θ (FIG. 9) formed at the light emitter 217 side end of the light shielding cylinder 219 may be appropriately set to, for example, an acute angle so that reflection of external light can be suppressed. Preferably, the value is smaller than the angle between the longitudinal direction and the horizontal direction.

  The light shielding cylinder 219 is formed, for example, by mixing black powder such as carbon black with polyacetal resin (POM), which is a light shielding material. It is possible to further suppress external light from transmitting through the light shielding cylinder 219 by changing the compounding ratio of the compounding component such as carbon black or changing the thickness of the light shielding cylinder 219. The cross section in the radial direction of the light shielding cylinder 219 may be a polygon such as a triangle or a quadrangle other than the form of a circle as described above. Also, for example, a flange in which the light shielding cylinder is divided along the longitudinal direction may be connected to the light receiver 218 instead of the light shielding cylinder to protect the light receiver 218 from external light. According to this configuration, as in the light shielding cylinder, it is possible to avoid the accumulation of paper dust and dust in the cylinder.

  FIG. 11 shows another example of the light shielding cylinder 219. An annular groove B is formed on the inner wall (inner surface) of the light shielding cylinder 219. If the groove portion B is formed by, for example, a screw groove, the light shielding cylinder 219 can be formed by resin molding or tapping. Another member having the groove B may be inserted into the light shielding cylinder. FIG. 12 shows the groove B in an enlarged manner. The groove B is, for example, a triangular V-shaped groove, and the larger the difference between the height of the groove and the height of the groove within the range not obstructing the optical path of the light emitted from the light projector 217, the better. Even if the external light 600 is reflected by the end of the light shielding cylinder 219 on the light emitter 217 side and the external light 600 reaches the inside of the light shielding cylinder 219, the external light inside the light shielding cylinder 219 differs from the light receiver 218 side by the groove B. It is reflected in the direction and attenuated. If the annular groove B is triangular, the slope on the incident side of the groove B is not visible behind the groove B itself as seen from the light receiver 218, so external light is reflected toward the deep part of this slope To repeat, it is attenuated without reaching the light receiver 218. Even if external light reaches the light receiver 218, the influence on the light receiver 218 is small because the light is sufficiently attenuated.

  FIG. 13 shows still another embodiment of the light shielding cylinder 219. As shown in FIG. As described above, the end of the light shielding cylinder 219 on the light emitter 217 is configured not to intersect the incident direction of external light, and the annular groove B described above is formed in the light shielding cylinder 219. There is. Therefore, according to the light shielding cylinder 219, even if the reflected light, not the direct light of the external light, enters the light shielding cylinder 219 from the end of the light shielding cylinder 219 at the light projector 217 side, the external light is transmitted to the light receiver 218 It is possible to further suppress reaching.

  FIG. 14 shows still another embodiment of the light shielding cylinder 219. As shown in FIG. A light transmitting member C is filled in the light shielding cylinder 219. The light transmitting member C is formed, for example, by injection molding of acrylic resin or polycarbonate resin capable of transmitting the output light from the light projector 217. The light shielding cylinder 219 can be obtained by molding a light shielding resin or coating a molded light emitting resin with a light shielding material such as a metal film. By making the inside of the light shielding cylinder 219 solid, paper dust, dust and the like can be prevented from accumulating in the light shielding cylinder. By forming the above-described annular groove B on the outer peripheral surface of the transparent member C and coating the outer peripheral surface with a light shielding material such as a metal film, attenuation of external light by the annular groove B can be realized. .

  (Fig. 9) of the end of the light blocking cylinder 219 at the side of the light projector 217, considering the critical angle of air and the light transmitting member C, the light from the light projector 217 is totally reflected at the incident angle of external light By setting so as to be able to be incident, the angle θ can be relaxed to the obtuse angle side as compared with FIG. 9, and the total length of the light shielding cylinder 219 can be shortened.

  FIG. 15 shows still another form of the light shielding cylinder 219. As shown in FIG. The light shielding cylinder 219 is provided with a flange D on the side surface of the light receiver 218 side end. The flange D is connected to the light receiver 218 so that the light emitter 217 side end 219A of the light shield cylinder 219 is in the direction of gravity by being configured to be positioned and mounted on the side surface of the light receiver 218. can do. For example, a hook may be formed on a part of the flange D so that the hook can be fixed at a specific position on the side wall of the light receiver 218.

  Another form of the light receiver 218 is shown in FIG. A light shielding member E is added around the light receiving portion 218A of the light receiver 218. The light shielding member E covers the side surface of the light receiver 218 and is formed of the same material as the light shielding cylinder 219. Since the side surface of the light receiver 218 is integrally molded with the lens of the light receiver 218A, when the external light reaches the side surface of the light receiver 218, the external light passes through the side surface of the light receiver 218 and the light receiver 218A is mistaken. May be activated. Therefore, by providing the light shielding member E so as to cover the side surface of the light receiving portion 218A of the light receiver 218, the light receiving portion 218A can be protected from external light.
